Film-type audio output apparatus

ABSTRACT

A film-type audio output apparatus includes an audio output device, at least one speaker unit, and at least one film. The at least one speaker unit is positioned at any side of the audio output device. The speaker unit can be an embedded speaker unit. The at least one film can be positioned at any or more places of an inner side and an outer side of the audio output device. When the speaker unit of the audio output device releases sound, the film positioned on the audio output device can get vibration of the sound so that the inside of the audio output device can generate resonance. Thus, the audio output apparatus can generate softer undertone and wider diapason.

The current application is a divisional application of, and claims a priority to U.S. Ser. No. 11/668,447 filed on Jan. 29, 2007 now U.S. Pat. No. 8,073,177.

BACKGROUND

1. Field of the Invention

The present invention relates to a film-type audio output apparatus and, more particularly, to an audio output apparatus with at least one soft or elastic film positioned at any or more places of an inner side and an outer side thereof so as to have efficacies such as softer undertone and wider diapason.

2. Description of the Prior Art

At present, there are various speakers in the market. A known speaker generally includes a speaker box and at least one speaker unit positioned at the front side of the speaker box. When the speaker unit begins to work, it can release the sound and the consumer can thereby listen to various music styles.

However, most of the speaker boxes purchased by the consumer cannot exert the sound effectively via the known structures and cannot generate resonance of the sound. Also, the diapason of the sound of the speaker boxes is not wide enough. Therefore, the consumer cannot obtain high-grade feeling in listening, though a lot of money has been spent.

What is needed, therefore, is an improved film-type audio output apparatus.

BRIEF SUMMARY

A film-type audio output apparatus according to an embodiment of the present invention includes an audio output device, at least one speaker unit, and at least one film. The at least one speaker unit is positioned at any side of the audio output device. The speaker unit can be an embedded speaker unit. The at least one film can be positioned at any or more places of an inner side and an outer side of the audio output device. Alternatively, a combined part combining the film can be positioned at any or more places of the inner side and the outer side of the audio output device.

Alternatively, the film-type audio output apparatus includes a combined part positioned at any or more places of the inner side and the outer side thereof, and the combined part combines the at least one film. Secondly, the present invention provides a film-type audio output apparatus that can be applied to various audio output apparatuses, or various products relating to sound, so as to improve quality of tone, sound effect and diapason of the products, and improve popularization, actualization and usage of the products. Thirdly, the present invention provides a film-type audio output apparatus that is simple in structure and manufacture and is low in cost.

The above description is given by way of example, and not limitation. Given the above disclosure, one skilled in the art could devise variations that are within the scope and spirit of the invention disclosed herein, including configurations ways of the recessed portions and materials and/or designs of the attaching structures. Further, the various features of the embodiments disclosed herein can be used alone, or in varying combinations with each other and are not intended to be limited to the specific combination described herein. Thus, the scope of the claims is not to be limited by the illustrated embodiments. 

What is claimed is:
 1. A film-type audio output apparatus, comprising a speaker unit having a protector on the speaker unit; an earphone structural part having at least one gas-permeable hole to release sound pressure; an earphone net cover; at least one elastic film positioned at a predetermined place between the earphone net cover and the speaker unit to have a softer undertone and wider diapason; and an aperture disposed at the center of the at least one elastic film to release sound pressure.
